JOHN A. VILSON, OF VOROESTER, MASSACHUSETTS, ASSIGNOR TO JOSEPH l It.TORREY, OF SAME PLACE.

RAZOR-STROP.

SPECIFICATION forming part of Letters Patent No. 348.486, dated August3l, 1886.

Application tiled June 17, 1885.

To a/ZZ whom, it may concern.-

Be it known that I, JOHN A. WILsoN, a citizen ofthe UnitedStates,residing at Vorces' ter, in the county of \Voreester and State of5 Massachusetts, have invented certain new and useful Improvements inRazor-Strops,of which the following is a specification, reference beinghad therein to the accompanying drawings.

The object of my invention is to dispense with the tension-screwsheretofore employed for adjusting the rigid blocks or plates by whichthe stropping-belts of razor-strops are tightened, by providing` inplace of said screws springs acting on said blocks or plates in such amanner as to hold the stropping-belts taut. By dispensing with theadjusting tension screws heretofore employed the liability of strainingor breaking the stropping-belts in 2O tighting the latter by applyingtoo much force to the screws will be avoided. In the drawings, Figures land 2 are longitudinal sections at right angles to each other of arazor-strop embodying my invention, and Fig. 8 isa longitudinal sectionshowingamodiieation.

A indicates the rigid wooden body-block of the strop, and B the handlethereof.

Gis thestropping-belt passing overabridge- 3o piece c at one end of thestrop, and over a tighteningplate, I), at the opposite end thereof, saidbelt being thus supported clear of said body-block on the opposite sidesof the latter. The tightening-plate is preferably provided with theusual steady-pins, d, entering holes in the block A, and said plate isforced outward to tighten the stropping-belt by one or more tighteningor tension springs, E.

In Figs. I and 2 the tightening-spring is Serial No. 168,986. (Nomodel.)

shown as surrounding a pin, d, attached to 4o the plate D, and enteringa hole in the block A; butin the construction shown by Fig. 5 thetightening-spring is placed in a socket in the block A behind a stem orplunger, d2, attached to or abutting against the plate D.

It will be understood that the spring E will be of proper strength orstiffness to hold the stropping-belts sufficiently taut for use, and assaid springs exert a yielding pressure on said belts the latter will notbe strained or 5o broken, as sometimes occurs with thetightening-screws.

I do not wish to be understood as limiting myself to the preciseconstruction herein shown and described, as the arrangements of 5 5 theparts may be varied somewhat withoutdeparting from the spirit of myinvention.

' The tighting-plates and their springs, instead of being arranged atthe ends of the strops opposite to the handles, as herein 6o shown, may,if desired, be at the handle ends of the strops.

I claim as new and desire to secure by Letters Patent- In a razor-strop,the combination, with a 65 body-block, and a stropping-belt supportedclear of said block on the opposite sides of the latter, of a rigidtightening-plate movable lengthwise of said block, and a spring forforcing said plate outward against said belt, 7o substantially as setforth.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN A. VILSON.
